two-level storage
解釋
二級存儲器-
First, the energy would diffuse after multiple frames accumulation and bring agglomeration effect. second, the amount of calculation and storage level are huge when the snr is low, especially the number of accumulated frames is large. to solve the problems, two methods have been resorted
但由於其本身存在著不足，一是多幀積累后能量擴散，產生團聚效應;二是在信噪比較低時，需要積累的軌跡很多，存儲量和計算量都較大，尤其是當積累幀數較多時。 -
This paper evaluates the underground water resources and its safe levels of miming, and then studies the availability of molepipe drainage, a kind of practical underground water regulation technique. starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well - studied determination method of determining the two hydrographical coefficients : rainfall infiltration replenishment rate and irrigation replenishment rate. then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage, exploitation on water regulation
論文從灌區的地下水資源及其可開采量評價分析方面入手，在對兩個主要的水文地質參數即降雨入滲補給系數、灌溉入滲補給系數確定方法研究的基礎上，對灌區的地下水資源狀況進行分析，依據灌區的灌溉、降雨、排水條件及各種現狀因素，建立了地下水資源量計算的數學模型，西安理工大學工程碩士專業學位論文計算得到青銅峽灌區地下水的最大補給量和可開采量;另外對在開發利用地下水資源過程中的地下水位的調控進行了初步的探討，在銀北灌區開展對暗管排水調控地下水位的試驗研究。 -
1. building aerial gamma - ray spectrometric database developed with sql server 2000 database management system, the entity - relation model of aerial gamma - ray spectrometric database is designed. a two - level storage structure is adopted to store aerial gamma - ray spectrometric survey data so as to shorten data rebundancy maxmimumly
建立航空伽瑪能譜數據庫以sqlserver2000數據庫管理系統為開發平臺，設計了航空伽瑪能譜數據庫的實體?關系模型，採用兩級存儲結構來存儲航空伽瑪能譜測量數據，最大限度地降低了數據冗餘度。 -
The two - level storage structure consists of basic information table of survey area and data table of survey spot, both of which is related by serial number of survey area
兩級存儲結構為測區基本信息表和測點數據表，通過測區編號建立對應關系。 -
With regard to the buffer storage of the module, a new method called two - lever buffer structure is adopted, in which the fpga ‘ s internal ram cells is the first level buffer and the sdram of embedded system is the second level buffer
2 .在設備的緩存方案上採用二級緩沖結構，利用fpga內部提供的存儲器單元作為第一級緩沖，利用嵌入式系統中的sdram作為第二級緩沖，實現了多通道、大規模緩存技術。 -
At the same time, the implemental approaches of the genetic algorithm for water supply systems including both fixed and variable speed pumps were introduced. the direct optimal operation model and two - stage optimal operation model of water supply systems with one or more tanks were proposed, according to the hydraulic characteristic of storage tanks. appropriate fitness function of genetic algorithm was designed to solve upper level optimization and lower level optimization in two - stage optimal model
在分析了蓄水池數學模型的基礎上，建立了含有蓄水池的供水系統優化調度二級尋優模型和直接優化模型，並設計了遺傳演算法適應度函數分別求解二級尋優模型中的一級、二級尋優，針對二級尋優出現無解的情況，提出了放鬆約束處理和對一級尋優得到的最優水池水位進行修正的方法。
